| Abstract: |
| According to the features of short signal duration and difficult bit synchr
onizaiton in burst communication, the Maximum Mean Power Estimation(MMPE) bit sy
nchronization method is studied,that is estimating the best sampling point b
y use of the sampling time with maximum mean power.The impact of length of obser
vation time on synchronizatio
n is simulated with MATLAB.The MMPE
method is realized based on FPGA and DSP. The test result shows that the dithe
r range is less than 8% of the symbol period. |
